Anti-Misplug Mechanism
The insulator's outer circle features keyways at various angles, allowing the manufacturer to transpose and assemble per user requirements. This ensures precise alignment, preventing mistaken insertion of plugs and sockets of the same specification, while enabling correct insertion of those with matching assembly numbers.
